Wednesday, July 26 – 7 p.m.

Your Local Weather Authority has issued a Weather Authority Alert Day starting at 2 p.m. on Thursday, July 27 that will expire at midnight on Saturday, July 29.

Over the next three days, southwest and central Virginia will see the year’s hottest temperatures thus far.

Along with the heat, storms will fire up on Thursday, Friday and Saturday. A few will have the ability to pack a punch and could bring localized flooding and damaging winds.

Expect higher temps

Peak heat index values (”feels like temperatures”) will reach 90-95°F in the Highlands and the New River Valley. Temperatures will feel like 95-100°F along I-81 and 100-105°F in parts of the Roanoke Valley, Lynchburg, and Southside.

Feels like temperatures could reach the triple digits in certain areas

A marginal risk includes most of our counties on Thursday. Showers and thunderstorms will build through the early afternoon with mature storms developing by the mid/late afternoon. Some isolated storms will cause localized flooding and have damaging winds.

Marginal risk in most areas

Here is a look at the FutureTracker showing isolated storms at 6:00 p.m. Thursday.

Rain moving through the area

The pattern of daytime heating with high temperatures getting near the triple digits will last until Saturday afternoon. High pressure to our south and west is funneling in winds that are bringing higher humidity and hotter air into our region.

With the addition of low pressure to the north and east, winds at the upper levels are converging along the Ohio Valley. As these systems track toward the east, we will have the potential to see severe weather.

High pressure to the SW aids the heat. Converging winds and Low pressure to the NE aid in storm development
